SPECIFICATION forming part of Letters Patent No. 230,066, elated July 13, 18 80.

Application filed May '1, 1880. (No model.) Patented in England December 1, 1879. I i

To all whom it may COG'LCGWI.

Be it known that I,Jon1v JAMES BOYLE, of "[1 Market street, Manchester, county of Lancaster, England, a citizen of the United Kin door of Great Britain and Ireland, have invented an improved Engincdanbricator, for which I have received Letters Patent in Eng land, No. 4,901), dated December 1, 1879; and I do hereby declare that the followiugis a full, clear, and exact description of the invention.

As applied to lubricating a stcaineugine cylinder, i arrange a communication by'a suitable'pipc from the middle of such cylini er, or thcreabout, to the main steam-su iply pipe, through a pair of cones or combination of parts .siinilartothoseinsedsin anhing'ector, in such.

manner that as the steam passes the cones a vacuum or partial vacuum is produced, which I utilize for the purpose of inducing the oil'to enter the cylinder. Suitable means are pro vided to feed the oil to the steam-jet in regular and measured quantity.

in the accompanying drawings, Figure. 1 represents side sectional view of my improved engine-lubricat. r, and Fig. 2 shows the method of connecting the same to a steam-engine cylinder, drawn to a reduced scale.

in both the views A is the body or injector portion oi" the inbricator, provided with the cones i3 and G. The inlet-cone B, I prefer to place in direct communication with the main steainsupply pipe D of the engine, and I prefer that the rear of the outlet-cone 0 should communicate with the enginia-cylinder E about the middle in horizontal c linders and the upper end in the case of ertical cylinders. The suction produced by the steam, passing those cones l utilize to draw in the oil or other lubricant, which I cause to fall onto the cup F, as hereinafter described. A valve, G, is arranged to prevent the return of the oil.

ll is an oil cup or receiver mounted upon thebracket l, projecting from the inj actor-b0 dy A, and provided with a loose cover, J.

K is a regulator for controlling the quantity of oil to the cup F, and consequently the quantity fed to the engine. This regulator K consists of a screwed cap, which can be made to more or less cover a small hole, a, in the tube L, and so regulate the quantity of oil dropping on the cup F to the greatest ninety.

tlironghthe cones B and U. and the 'suction produced thereby opens the valve G and drawsin any oil that may have been fed to the cup F and carries it into the cylinder E'. .At the period of high pressure in the cylinder the 6o valve G closes, and so prevents the oil returning.

in Fig. 3 1 illustrate the same lnbricator arranged for locomotive and other engines which work intermittent] y, and in which the fee'd'ot' In this case the oil-cup H is mounted directly over the body A,

oil is not visible, as in Fig. 1.

andthe check-valve G has a long spimlle,( passing up through the tube (M, and which valve is hold up to its seat by 'a spring,'().- A sleeve, lflfits round the tube M, and its lowerpart is formed as a plug-tap, with a small .holcf 1t, correspondiu to a similar liole in the fixed F tube M.

By turning the sleeve 1, by means of the milled head S, the amountof passage through the hole It may be varied, and consequently the oil passing to the valve G regulated to the greatestnicety. The relative position oi the holes is shown by a pointer, 'l, sweeping over an index, U.

V is a loch-nut for fixing the sleeve P in position.

It will be seen that the lower portion of the tube M, Fig. 3, performs the functions of the cup F, Fig. 1, andthe main part of said tube M, from the bottom of the cup H upward, perlorzns the-functions of the tube L, while the sleeve 1" performs those of the cap K. The upper neck of the iujector body A receives the enlarged and threaded lower end of the tube M in place of the cup F, and a plain screwcap, X, of alike pattern at its inner end, takes the place of the scrcw-cap to which the bracket I is attached. Theinjector-body A is the same iii-both cases, and its interior is clearly shown in Fig. 1.-

In each form of my lubricator a regulated escape of the lubricant from the cup H, say one drop per stroke, passing by gravity to the oil-inlet of the injector A, is carried into the cylinder E by injector-action at each succeeding period of low pressure without reliance upon the slow flow of the lubricant and with out the manipulation of any cook or valve by the engineer, the entire operation being auto matic.

I am aware that an engine-lubricator has been constructed with a steam-connection, so as to provide for blowing the oil from a hollow cock when the latter is opened.

My lubrieant-injector, with suetionconcs, does not depend on any opening or closing of cocks, but, as applied to a steanrengine, operates automatically while the steam is on, as aforesaid, under the control. of the pressure in the cylinder, and the injector action is superior in that it carries the lubricant into the cylinder in the form of spray, and thus facilitates its access to every part of the circumference of the cylinder.

I am also aware that check-valves similar to my valves 0, and also an escape-regulator con sisting of one perforated tube within another, have been used in other lubricators.

. In my combinations the valve G is opened and closed by the injector-jet under control of the pressure in the cylinder, and the escaperegulator K L or I M simply controls the passage of the lubricant to the inlet ofthe injector A,- from whence it is carried into the cylinder by injectt '-action, as aloresaid.

Although I have found the method of fixing thelubrieator herein described to give the best results in practice, I would observe that it is not essential that the steam-supply be taken from the main steam-pipe, as it may be taken from the valve-box of the engine or from either end of the cylinder.

.It will be obvious that thisarrangement ol' lubrieator is also applicable for lubricating of a cup for supplying the lubricant, means for regulating the escape from said cup, and an injector having suction-cones, an inlet for the lubricant, an inlet for the steam or its equivalent, and a connection with the enginecylinder, arranged and operating substantially as herein described, the lubricant being carried into the cylinder by injector-action, as set forth.

2. The combination, in an euginelubric ator, of a cup for supplying the lubricant, means for regulating the escape from said cup, and a checlev'alve with an injector having suctioncones, an inlet for the lubricant, an inlet for the steam or its equivalent, and a connection with the engine-cylimler, substantially as herein specified.

3. Thercgulating-sleeve P It, Fig. 3, in combination with the supply-cup Ill, having the inelosed escape-tube 'M, the check-valve G, seated at the lower end of said escape-tube, and the injector A, substantially as herein specified, for the purposes setforth.
